Each mailbox has a Safe Senders list stored within it. You can add trusted senders to this list, affecting only that specific mailbox. Email addresses and domain names that you add to your Safe Senders list are not treated as junk email.You can add your Contacts and other correspondents to the Safe Senders list to confirm you'll always receive their messages in your inbox.  

A few considerations:

  • Remember that messages identified as malware or high-confidence phishing are always quarantined regardless of safe sender settings. 
  • Be cautious when making exceptions to spam filtering using safe sender lists and always submit messages for analysis. 
  • Additionally consider blocking email from specific sources using blocked sender lists if needed.

Below are instructions for Outlook, the ITS-supported WPI email application. For other email providers, please search their Help for safe sender or whitelist instructions.

Safe Senders List (Outlook.com or Outlook on the web):

Add recipients of your email messages to the Safe Senders List:

This ensures that their emails are never treated as junk, regardless of the message content, per Microsoft.

  1. Click on the Home tab. 
  2. Select Junk, then click Junk E-mail Options.
  3. On the Safe Senders tab, check the Automatically add people I e-mail to the Safe Senders List box.
    • Optionally, you can also add contacts manually to the Safe Senders List.
    • Remember that this setting doesn’t automatically include contacts in the Safe Senders List.

Outlook Contacts:

By default, email addresses in your Outlook contacts are considered safe senders by the Junk Email Filter.

However, you can change this setting if needed.

If you send a message to someone who isn’t an Outlook contact, their email address won’t be added to the Safe Senders List automatically. Be aware that their replies might end up in the Junk E-Mail folder.

Additional Tips:

If you’re using Microsoft Exchange Server, mailboxes in the Global Address List (GAL) are also considered safe senders.

Consider using mailing list rules to handle messages from mailing lists without classifying them as junk.

If you accidentally mark an email as junk, you can find it in your Junk Email folder and mark it as Not Junk.

Keep in mind that junk email is retained for 30 days before automatic deletion.
